To power up a 2U expansion enclosure, install the power cords and check the
status LEDs on installed canisters.
About this task
Use either the rack PDU power cords that are supplied with the expansion enclosure, or the
country-specific power cords bought as an option. Two cords are required.
Procedure
To power on the system, complete the following steps.
- Power on the control enclosure by connecting both power supply units of the enclosure to their
power sources, by using the supplied power cables. If the power sources have circuit breakers or switches, ensure that they are turned on. The
enclosure does not have power switches.
Note: Each enclosure has two power supply
units. To provide power failure redundancy, connect the two power cords to separate power
circuits.
- Check the LEDs on each node canister in the control enclosure (see Figure 1).

The canister is ready with no critical errors when Power is illuminated,
Status is flashing, and Fault is off. If a canister is not ready, refer to Procedure: Understanding the system status using the LEDs.
